Cobalt leaching resistance of the solidified radioactive sludge subject to disposal was evaluated. The sludge powders ((Fe 2 O 3 ), NiO, and Cr 2 O 3 ) with non-radioactive cobalt powder was homogeneously mixed with ferro frit and treated in hot isostatic pressing process. Although the mixing ratio...
